Domain-Driven Design for complex business domains. Use when deciding whether DDD is warranted, defining bounded contexts, aggregates, entities and value objects, applying CQRS or domain events, or organizing a domain layer. .NET project and solution layout is dotnet-solution-architect.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Domain-Driven Design Architecture Decide whether DDD is warranted, then load the one reference that owns the pattern. Do not implement a base class or a library layout from this file. ## When to Engage User DDD is highly context-dependent. ALWAYS discuss with user before implementing. If this skill is invoked from `saas-workspace-initializer` Step a2, the Round 1 discovery answers (jobs-to-be-done, candidate domains, MVP scope) are already available — use them and do not re-ask the equivalent questions. Ask only what those answers leave open. Load [references/discovery.md](references/discovery.md) only when domain discovery is still open. ## Warrant Score with the user before writing pattern code. Count the yeses: - Do entities have complex lifecycles? (draft → approved → fulfilled) - Are there business rules that span multiple entities? - Do different parts of the system use different terminology? - Is there a need for audit trails or event sourcing? - Will multiple teams work on different parts? | Yeses | Do | | ----- | -- | | 0-1 | Simple services. Stop. | | 2-3 | Tactical patterns only (entities, value objects). | …

How to install
mdr add hive-academy/ptahcode/ddd-architecture@sha256:1e3615a055d997b3The line at the top of this page pins the label git:20261025.e12e11b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
